Villain is unknown.
On the flop a lot of worse hands can call. Like: TT-KK, KdQd.
He is an unknown, so I can't say if he is flatting SC or suited gappers pre-flop,
but I try to play ir very simple: just bet for a free show down on the turn.
Turn looks a lot like QQ or AQ. Interesting, if he could play AK this way.
